MIC23450
3MHz, PWM, 2A Triple Buck
Regulator with HyperLight Load® and Power Good
General Description
The MIC23450 is a high-efficiency, 3MHz, triple 2A, synchronous buck
regulator with HyperLight Load® mode. HyperLight Load provides very-high efficiency at light loads and ultra-fast transient response which is perfectly suited for supplying processor core voltages. An additional benefit of this proprietary architecture is very low output ripple voltage throughout the entire load range with the use of small output capacitors. The 5mm x 5mm QFN package saves board space and requires only five external components for each channel.
The MIC23450 is designed for use with a very small inductor, down to 0.47µH, and an output capacitor as small as 2.2µF that enables a total solution size, less than 1mm height.
The MIC23450 has a very-low quiescent current of 23µA each channel and achieves as high as 81% efficiency at 1mA. At higher loads, the MIC23450 provides a constant switching freque...
